Filed: 1948-04-16
Abstract: 670,320. Discharging fish. HUMPHREYS, H. R. April 16, 1948. No. 10604/48. Classes 78 (i) and 78 (iv). [Also in Group XXXIII] A method of handling fish comprises collecting in a receptacle a quantity of fish mixed with a sufficient amount of water to render the mass fluid, pumping such fluid mass from the receptacle to an elevated point, separating the water from the fish at such point and returning the water thus separated to said receptacle, whereby the same water is continuously recirculated until the supply of fish is exhausted. Fig. 1. Fish mixed with water in hold 2 of the boat is impelled by water jets 26 and 31 into channel 4 whence it is discharged up suction pipe 11 by pump 13 and flows thence up pipe 14 into rotating screw conveyer sieve 15, the water draining into tank 22 which feeds it tc pumps 24 and 29 which supply the jets 26 and 31 so that the water is recirculated. The fish from sieve 15 are discharged into measuring device 17 and then are conveyed away by screw conveyer 20. Pipes 26 and 11 are fixed on the boat and are connected by flexible pipes 25 and 12 to the pumps 24 and 13 fixed on the wharf. Pipe 31 is flexible and constitutes part of the wharf equipment. The water flows into channel 4 first through aperture a which is left open and, after all the fish in that part of the hold has been discharged, plug 8 is lifted from aperture b and dropped over aperture a, and so on till the fish in all parts of the hold are discharged. Specification 670,319, [Group XXXIII], is referred to.

Title: Process of distillation
IPC: C07C45/81
Filed: 1943-07-09
Abstract: 572,843. Distilling vinyl derivatives. IMPERIAL CHEMICAL INDUSTRIES, Ltd. (Du Pont de Nemours & Co., E. I.). July 9, 1943, No. 11155. [Class 32] In a process for separating a monomeric liquid compound containing the group H2C=C< from admixture with non-volatile impurities (e.g. a polymerisation inhibitor such as sulphur or copper resinate), the impure liquid is supplied continuously or intermittently to a heat transfer medium or zone, maintained at a temperature above the boiling point of the compound under the prevailing conditions, at such a rate that substantially the whole of the compound is vaporised by flashing. Preferably, particularly when the liquid contains a volatile peroxide as impurity, the flashing is carried out at a temperature which is 50‹C. or more above the boiling point of the compound; the peroxide is thereby destroyed. Preferably also, the flashing is carried out under conditions where the liquid has a lowered boiling point, such as by the use of reduced pressure, or steam distillation. Compounds to which the process can be applied are methacrolein, methacrylic acid, acrylates, methacrylates, ethacrylates, styrene, and vinyl acetate. In examples (1) Vinyl acetate is flashed at atmospheric pressure using a heat source at about 110‹C. (2) Methacrylic acid nearly free from peroxide is obtainable by flashing under a pressure of 20 to 30 mm. with a heating surface maintained at 100‹ to 120‹C. When the methyl ester is to be purified the same temperature may be employed but under a pressure of 100 to 125 mm. (3) Styrene is freed from copper resinate by steam distillation. The liquid to be distilled is supplied by pipe line 13 fitted with valve 14 into a pot still 11 equipped with heating jacket 12 through which steam or the like may be passed to obtain the desired operating temperature. The vapour line 15 leads to a condenser 16 which discharges into a receiver 17 connected through line 18 with a vacuum pump. By adjustment of valve 14, the rate of inflow of liquid into the still is regulated so that it is equal to the rate of vaporisation. The operation is interrupted from time to time for the purpose of removing the residue of non-volatile impurities which accumulates in the still. A plurality of stills and condensers may also be employed; the liquid may be heated by a jacket before entering the still and a packed column may be inserted between the still and condenser.
